Kliminrichting voor gebruik op een hellend dakvlak en werkwijze voor het werken op een hellend dakvlak.

摘要

The ladder (1) has a pair of uprights (3) joined together by standing surfaces (4), and components positioning it on the roof (2). Supports (7) hold the rear edges (6) of the standing surfaces clear of the roof surface (2) in the working position. The standing surfaces can consist of steps, and the uprights can protrude over part of their length at the side towards the roof beyond the step rear edges. They can form protruding feet at right angles to the step surfaces and bearing against the roof. The gap between the step rear edges and the roof can be adjustable.
